    An important quality factor of the frequency sources is the far end phase noise power spectral density S_φ(f). i.e. the phase noise power spectral density at Fourier frequencis higher than 6KHz. Due to the fact the values of S_φ(f) are very low in this frequency range, it is necessary to measure them by a test set with very low testing threshold. The threshold of the test set designed by the ordinary phase detecting principle may be as low as necessary, but there are some significant shortcomings in it....

    An important quality factor of the frequency sources is the far end phase noise power spectral density S_φ(f). i.e. the phase noise power spectral density at Fourier frequencis higher than 6KHz. Due to the fact the values of S_φ(f) are very low in this frequency range, it is necessary to measure them by a test set with very low testing threshold. The threshold of the test set designed by the ordinary phase detecting principle may be as low as necessary, but there are some significant shortcomings in it. These are:(1) a high frequency, broadband and variable phase shifter is always required in this kind of apparatus; (2) a syncronization in frequency of the tested signal and the local frequency standard is required so the apparatus is quite complicate, bothersome in adjustment when in use, and its scope of usuage is quite therefore limited. In this paper, a new method of measurement is suggested, in which the shortcomings stated above may be overcome to a great extent while the testing threshold and accuracy (confidence interval) are almost the same as in the ordinary phase detecting method. Its fundamental principles, confidence interval and testing threshold as well as the main points in design are analyzed and discussed. A test set designed by using this new principle has been made, with which the phase noise factor has been measured for a number of frequency sources. The results obtained in these measurements are in good agreement with the data outlined in the instructions of the frequency sources under test.

    频率源的远端相位噪声功率谱密度S(f)(此处指的是付氐频率f>6kHz的相噪功率谱密度),是一个重要的性能指标。由于在这f段的S(f)值甚小,故必须用“测试低限”很低的测试设备。用一般鑑相法制成的设备可能达到这一“测试低限”,但却存在以下缺点: (1)需用高频宽帶可变移相等部件;(2)要求待测源与设备内部的本振源严格同频。这些缺点导致了设备的应用范围受到限制,并使其结构变得比较复杂,因而调节、使用不够方便。本文提出了一种新的方法,它具有与上述鑑相法制成的设备同等级的“测试低限”和测试精度(置信区间),却又基本上克服了其缺点。文中阐述和讨论了新方法的基本原理、置信区间、测试低限和设计的重点。利用按新方法制就的设备,对多种频率源进行了实测,所得结果与其说明书中所述相符。

    With the development of optical fiber communication technique, the requi-rements on the quality of optical fiber are more and more severe. Among thequality indices of optical fiber, the uniformity of fiber diameter and the mag-nitude of tension are critical, since variations in fiber diameter and tensionappreciably affect the optical and mechanical properties of optical fiber. Inorder to satisfy the requirements of optical communication, it is highly neces-sary to control completely the factors affecting fiber performance. Consideringthese factors, we have developed a high speed Optical Fiber Drawing ProcessMicrocomputer Adaptive Control System (OFDPMACS). In this paper, wediscuss the design and implementation with a dual-microcomputer of OFDPMA-CS. Aimed at the requirements of high precision and high speed on the draw-ing of optical fiber, we propose a new self-tuning control algorithm based onoutput prediction. The fiber diameter can be controlled within the range of125±0.5μm with such an algorithm. The result is much better than that ofPID controller. The tension of optical fiber is another important quality index.However, there are many factors affecting the tension and a suitable mathe-matical model is difficult to build. In order to avoid the difficulty, we employexpert system and fuzzy mathematics and present Expert Intelligent Control(EIC) scheme for the above-mentioned complex dynamic system. The EICconsists of knowledge base, inference engine, recognition engine, and fuzzycontroller. Applying the EIC method, we solve the problem which conventionalmethods find impossible to solve. For implementing this system, we choose the IBM-PC microcomputer andDJS--041 single board computer with Z80 CPU to construct a dual-microcomputercontrol system. In order to meet real-time requirement of the control system,the high speed Numeric Data Processor Intel-8087 is employed. The real-time control software is programmed with high-level language FORTRAN77, and this software has high reliability and is easy to program, debugand modify. The OFDPMACS has a friendly man-machine interface which consists of an easy-to-learn operating system, thus operators can findout the operating states of the drawing process in time. And this interfacemakes it convenient to recognize the faults and recover them automatically. TheOFDPMACS has been put into practical use, and satisfactory results havebeen obtained.
